Microsoft releases ISO for Windows 10 Redstone 4 build 17025

Microsoft just released the ISOs for Windows 10 Redstone 4 Build 17025. You can use the ISOs to perform a clean install or to check out the progress with Redstone 4 on a virtual machine.

You will not find so many new features in the early Redstone 4 builds, but the company made a few changes along with several improvements to the operating system.

The company added some new Fluent Design changes to the operating system just as expected.

Just to refresh your memory, Redstone 4 is the codename for the next feature update to Windows 10. It is scheduled to arrive to the users sometime next spring.

Since there’s still plenty of time before its launch, there are apparently not a lot of features that can be found in the previews yet. The latest build brought a few changes targeted at Cortana. Before that, the company added Cortana Collections.
